Additional information
Formula for the calculation of PNECsed using the equilibrium partitioning approach for sediment:
PNEC(sed) = (Ksed-water x PNEC(aqua) / RHOsed) * 1000
PNEC(sed) Predicted No Effect Concentration in sediment [mg/kg, wet weight]
Ksusp-water partition coefficient sediment / water [1.20 m3/m3]
RHOsed bulk density of sediment matter [1150 kg/m3]
PNECaqua Predicted No Effect Concentration in water [as above]
Formula for the calculation of PNECsoil using the equilibrium partitioning approach for soil:
PNEC(soil) = (Ksoil-water x PNEC(aqua) / RHOsoil) * 1000
PNEC(soil) Predicted No Effect Concentration in soil [mg/kg, wet weight]
Ksoil-water partition coefficient sediment / water [0.925 m3/m3]
RHOsoil bulk density of soil matter [1700 kg/m3]
PNECaqua Predicted No Effect Concentration in water [as above]
Conclusion on classification
Because ethyl acetate is readily biodegradability and shows low acute aquatic toxicity and chronic toxicity NOECs are >1mg/l, it does not meet the criteria for classification for environmental toxicity.
